device packages Scope This part of IEC 60191 gives general rules for the preparation of outline drawings of surfacemounted semiconductor devices It supplements IEC 60191-1 and IEC 60191-3 It covers all surface-mounted devices discrete semiconductors with lead count of greater or equal to 8, as well as integrated circuits classified as form E in Clause of IEC 60191-4 Normative references The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated references, the latest edition of the referenced

Geometrical Product Specifications (GPS) – Geometrical tolerancing – Tolerances of form, orientation, location and run-out Terms and definitions For the purposes of this document, the following terms and definitions apply 3.1 seating plane plane which designates the plane of contact of the package, including any stand-off, with the surface on which it will be mounted NOTE This plane is often used as the reference plane 3.2 reference plane plane parallel to the seating plane at a distance A3 above seating plane (does not apply to leadless package) NOTE The distance A3 is known as the reference plane distance It determines the terminal projection zone (see Figure 1) NOTE This distance is a theoretical dimension which is not related to any feature of the package Its value is chosen for each package so the length of terminal projection zone L p is a good approximation of the terminal length used for mounting, e.g the length of the part of the terminal that is soldered to the substrate BS

position area maximum area on the seating plane within which the terminal projection zone is located, taking into account the maximum values of L p and b p NOTE The surface of the terminal position area is equal to l × b with, generally l = L p max + (HDmax – HDmin.)/2 = L p max + (HEmax – HEmin.)/2 and b = b p max + x NOTE Checking can be carried out by means of an appropriate gauge (see Figure 2) 3.4 pattern of terminal position areas group of all terminal position areas of a leaded package or folded lead package in the seating plane NOTE For a leadless package, it is the projection of its metallized pads or terminals on the seating plane NOTE The true positions of the centres of the terminal position areas are located on a grid with a modulus e / eD or e / eE NOTE The pattern of terminal position areas does not include tolerances stemming from mounting substrates (printed board) design and placement machine accuracy 3.5 coplanarity of terminals profile tolerance controlling the location of the crowns of the bottom terminals with respect to the seating plane NOTE In all the other cases, the requirement for coplanarity of terminals is clarified by a note 3.6 datum geometrical established planes for controlling the tolerance zone NOTE Datum S should be established by seating plane Design rules The outline drawing of a surface-mounted semiconductor device package shall comprise in the given sequence: – the drawing (strictly speaking); – the tables of dimensions; – the notes to the tables and the drawings; – the codification The drawing shall conform with the
